SPECIFICATION forming part of Letters Patent No. 679,374, dated July 30, 1901. Application tiled October 3l, 1900. Serial No. 34,991. (No model.)

To @ZZ whom it may concern:

Be it known that I, HENRY D. HIBBARD, a 'citizen of the United States, residing in Plainlield, in the county of Union and State of New Jersey, have invented certain new and useful improvements in Bolt Mechanism for Safe or Vault'Doors, of which the following is a speciiication.

This invention relates to bolt mechanism for safe or vault doors, one object of the invention being to provide improved bolt mechanism for'such doors.

vide an improved organization of bolt mechanism particularly adapted for oval-shaped doors.

1n the drawings accompanying and formj lng part of this specication, Figure 1 is a i rear View Vof this improved bolt mechanism, 'the back plate of such door being partly broken away more clearly to illustrate the mechanism. IFig. 2 is a vert-ical sect-ional i view thereof, 4taken in line a a, Fig. 1. Fig.

Fig. 7 is a partly sectional view of said looselymounted clutch member.

Similar characters of reference indicate correspondingr parts in the different )figures of the drawings.

One of the objects of the present invention, as hereinbefore stated, is to provide bolt mechanism particularly adapted for an ovalshaped door, and therefore door 2 in the present instance is of greater length than breadth and is shown provided with semicircnlar ends 3 and parallel sides 4 and is preferably oval in shape, this form being adapted to meet the demand for a door of this general shape which will not require as much floor-room in which to swing as a circular door. This door in the present instance comprises a body 5, having forwardly-extending lugs 6 for the reception of a hingepintle and a rearwardly-extending iiange 7, the periphery of which in the form shown forms a continuation of the pesupported Fig. 5 is a cross- Fig. 6 l

riphery of the body, whereby a continuous joint-surface is formed by such flange and body. To this flange the back plate Si, carrying the major part of the bolt mechanism, is secured. The flange 7 of the door is usually provided with an offset or step 9, coperating with a similar step or offset located in the jamb ot' the body-doorway. The flange 7 is provided at intervals around the same with a series of bolt openings or apertures 10, each preferably ot' tapering or flaring formation obtained by forming one side of each A further object of the invention is to proopening inclined, whereby lateral movement of the bolts during their longitudinal or radial movement is permitted. Each of these bolts 12 is shown comprising a head 13 and a shank 14. The bolt-heads work in the bolt-openings, whi-le the Shanks thereof are provided with apertures 15 for the reception of projections or pins carried by means shiftable to throw the bolts. This shittable means in the present instance comprises aseries of rocking devices 17, some of which are shown as sector shaped members 18, while others are shown as substantially semicircular members or plates 20,all having worm-teeth formed on their peripheries. The semicircular plates 2O are shown in the present instance as two lin number and Vlocated one adjacent to each end of the door and mounted on a suitable hub or projection of the back plate and each carrying a plurality of pins or projections 16 (shown herein as four in number) for the reception of the inner ends of four bolts, two working at the opposite parallel sides of the door and two working at the curved ends of such door. Intermediate these two sets of bolts are located the sector-shaped members 18 (shown herein as three in number) and each mounted upon a suitable hub or proj ection carried by the back plate. To each of these sector-shaped members the inner ends of a pair of bolts are pivoted, such sectorshaped member carrying a pair of pins or projections 16' for this purpose. It will be understood, of course, that any desired number of these sector-shaped and semicircular members or plates may be provided, corresponding in number with the desired number of sets of bolts to be used. For shifting these rocking members a pair of worm-shafts 23 IOO and 24 are mounted in suitable bearings on the back plate, one of said shafts in the present instance carrying three worms 25 in engagement with three of the rocking members, while the other shaft carries a pair of worms 26 in engagement with the other two rocking members. Each of the worm-shafts is provided at its inner end with a bevel or miter gear 27 in mesh with a similarly-formed gear 28, carried by a shaft 29, mounted in suitable bearings 30 on the back plate.' On this shaft 29 is located a loosely-mounted clutch member 31, having a gear 32, provided with spirally-formed teeth in mesh with a pinion 33, having similarly-shaped teeth located on the inner end of a spindle 34, which projects to the outer side of the door and by means of which said loosely-mounted clutch member 3l is rotated. Motion is imparted to the worm-shaft by means of a clutch member 35, splined to the shaft 29 and shiftable into and out of engagement with said loosely-mounted clutch member 31 by combination-lock mechanism, which in the present instance is shown comprising two combination-locks A, each connected with such splined clutch member 35 by a clutch-shifter 36. On the proper setting of the combination of either lock the shifter 36 will be actuated to shift the splined clutch member into engagement with the loosely-mounted clutch member, whereupon on the rotation of the spindle 34 the wormshafts will be rotated to actuate the rocking members, and thereby the bolts. Either one of the combination-locks in the present organization will operate the clutch -shifter. When one is being used for this purpose, the point of connection of the shifter 36 with the other combination-lock constitutes a fulcrum for such shifter. In the present instance the combination-locks are controlled by a suitable time-lock B, the mechanism of which is connected by a suitable lever system 40 with the fence of one and the bolt (not shown) of the other combination-lock, whereby when the time mechanism runs down this lever system will be operated to permit the operation of both combination-locks, so that either one of said combination-locks can be utilized to shift the clutch-shifter 36, and thereby the splined clutch member 35 into engagement with the loosely-mounted clutch member 31, whereupon on the operation of the spindle 34: the worm-shafts will be rotated to actuate the bolts. By this organization of time and combination locks the mechanism of the combination-locks are dogged in such manner that even though the combinations may be disclosed the possibility of opening the safe until the time at which the time-lock is set to run has expired is positively prevented. Afurther description, however, of this improved time and combination lock mechanism is not deemed necessary herein, since it constitutes the subject-matter of a separate application pending contemporaneously herewith, Serial No. 35,197, led November 2,

'faces of stops 51 and 52.

1900, and designated as locking mechanism for safes or bolts.

For properly guiding the bolts during the shifting thereof surfaces 50 are located in position adjacent to the inner ends of the bolts and upon which such inner ends slide, whereby improper play of the bolts is prevented. Y

To prevent the premature retraction of the bolts should the back plate be blown off under an explosive charge, suitable means are provided. This means in the form shown comprises a series of stops, one or more for each set of bolts. In the present instance a plurality of stops for each set of bolts is provided. In the construction shown those bolts which are swung downward in retracting have their inner ends or Shanks inclined, so as to engage corresponding inclined sur- It is to be understood, however, that other forms of stops may be used. Those bolts which, however, are swung upward in retracting abut when in their extended position against bosses or projectionsin amanner similar to that shown and described in my contemporaneously-pending applications, Serial No. 679,976, filed May 7, 1898, now Patent No. 662,428, dated November 27, 1900, and Serial No. 16,402, iiled May 12, 1900, now Patent No. 662,435, dated November 27, 1900.

From the foregoing it will be seen that a toggle action of the bolts is secured whereby in practice the door will be drawnto its seat with considerable force. In otherwords, owing to the combined radial or longitudinal and lateral movements of the bolts the faces of the bolt-heads which engage the surfaces of the safe or vault body are brought into engagement with such surfaces by a rotatable movement, so that such bolt-faces are shifted with a grinding action over such body surfaces,and consequentlya most powerful binding of the bolts upon the surfaces of the body is effected with a minimum amount of power applied to the actuating-spindle. Also by the use of worm-gearing the bolts are operated with great force, which is not possible with rack-and-pinion gearing.
